Astra requires multiple turns and fresh refactoring agents to produce good code.
Comment context
Once you add a good harness and some tools (python, websearch, ...) they become almost as capable as the latest top model for a fraction of the cost and can be run locally at decent speed.(for my use case, qwen 3.8 27b was already better than sonnet) I say almost because for some very hard problems i still believe fable 5.1 / opus 5.5 class of models have an edge. But for 99% of usecases where you don't try to solve frontier math problem or rewrite a whole new OS, they are irrelevant compared to newly released open sources models.

Or use Fable-5.1 to review, even better. That will be a model with more parameters, meaning it has better knowledge of rarer truths, and it will also have different pre-training and post-training.
Comment context
If Astra is that great, how come its code introduces so many bugs? Give Astra a complicated task on Ultra, and then after give the prompt "review" - you will get about 5 problems. Ask to fix those, then after review again and you'll get another 5. Should I just not bother sending the review prompt and hope for the best, and only ask to fix issues I notice myself?!
